is there any way to disable kernel messages on the console? The problem I have is that it is almost impossible to work on the console due to a flood of file system errors from the kernel.
I've checked /etc/syslog.conf and disabled kernel logging to the console. Even with syslog turned off the messages still flood the console.
What i'm trying to accomplish seems rather silly but is needed for my little project here.
I'm using OpenSuSE 11.2 as a media center PC and need it to login automatically(console not X). That one i accomplished without problems.
However, after login i can see all the info about the services that were started and that needs to "go away".
One could do a "clear" in the .bash_rc and or .bash_profile but it will still show the login prompt which i don't want to see either (i don't even want to see the blinking cursor as well).
Question: How do i accomplish that so that the login console shows only the "splash screen" without any output of the kernel,rc.status nor the "issue-file"... just a plain blank screen ?
I'm trying to stop all boot time messages from appearing -- basically I'd like to have a simple blank screen from grub to xdm.
I tried everything -- used the "quiet" option in grub's config, added dmesg -n 1 to rc.local, changed console=ttySx, set kernel.printk in sysctl.conf to 4 1 1 7, and even eradicated rsyslogd altogether... to no avail. I still see all sorts of messages on my screen.
after upgrading to 11.04, natty, I have a problem with rsyslogd.
In previous releases I went to:
/etc/rsyslog.d/50-default.conf
and uncommented the lines under comment:
# I like to have messages displayed on the console, but only on a virtual
# console I usually leave idle.
This was redirecting the log messages to a console I could get to via Ctrl-Alt-Fwhatever.
In natty, this no longer works. When I switch to the relevant console I get a blank screen with a blinking cursor.
The file /etc/rsyslog.d/50-default.conf still exists. A new arrival is also 50-default.conf.ucf-dist which, as far as I can tell is a clone and which I have also modified like 50-default.conf.
The file /etc/rsyslog.conf (configuration file for rsyslogd) exists and its last line reads:
$IncludeConfig /etc/rsyslog.d/*.conf
which presumably should force rsyslogd to read 50-default.conf at startup.
Looking at the running processes I can see that rsyslogd runs.
how can we store the console messages when linux system goes for reboot /is there any path that we can see these console logs. i need to check some ting on the console .

At initial boot i see the two penguins and text from th kernel scrolls past until my root partition is mounted where upon all messages stop until the console prompt or KDM pops up. Everything seems to be operating as normal but i've no idea whats happening during the rc scripts (FS checking, etc). When shutting down though the rc.6/rc.0 script messages appear in the console though.
To my knowledge i've not changed anything that would effect this (just modified inittab for runlevel 4 & tty4,5,6 in runlevel 4).
There's nothing in dmesg but most messages don't get logged there as i understand.
I've been getting messages, that should be in the dmesg log, on the console.This has been happening for a while, but I finally got tired of them.My system is Fedora release 14, Kernel 2.6.35.11-83 on an x86_64.When I reboot I get the following displayed with the login prompt.[ 52.492937] readahead-collector: starting delayed service auditd[ 52.795508] readahead-collector: sorting[ 53.033970] readahead-collector: finished

View 1 Replies View RelatedI am using Arch Linux and want to disable console messages which are displayed when the kernel boots. I have tried the quiet and loglevel=2 options in /boot/grub/menu.1st as given below:
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/c6dbfcdc-fcd8-498e-9182-f3bddc4f05ff ro loglevel=2
However I am still seeing console messages at boot. I used grub-install after the changes.
Any ideas where I am going wrong?
After grub loads the kernel I'll get an on screen message from the console showing: cannot reserve MMIO region And I was wondering is there a way to silence console messages so you don't see them at bootup?
Could setting dmesg work:-nlevel Set the level at which logging of messages is done to the console. For example, -n 1 prevents all messages, expect panic messages, from appearing on the console.So typing at a term 'dmesg -n 1' will work?
I want to know if there is a way to disable the GUI console on 10.04 Server I want the traditional pure text console ... no plymouth, no plymouth-theme, just 80x24 console. Another question, Is there a way to get those traditional messages when booting? Like 8.04 Server does?

Slackware 12.0 (GNU/linux kernel 2.6) I am said slackware is very stable (I suppose this means it has few bugs). However, every time I run startx to start the graphical interface, for a brief moment I can see (just before the screen is put in graphical mode) a lot of error messages. How can this be? I use slack 12 a lot and have reinstalled this distro many times. However the described behavior always repeats.

I need to debug a kernel panic. It prints some long log to the console, but even if i set 1920x1440 VESA framebuffer mode, i can't see it whole.
So, i would like to direct all the kernel messages to a COM port and read them on another machine. Is there any way of doing so? What are the other (maybe better/easier/etc.) ways of catching whole kernel panic messages or scrolling the ones already displayed?

View 1 Replies View RelatedWhen my computer shuts down, I always get a long error message from the kernel. It's the very last thing the computer does and I can't even use the keyboard, since the system is halted. I wanted to read it more carefully (it's very long and doesn't fit the screen) and file a bug report against the kernel with it. But for that, I needed to save all that text in a file.
View 1 Replies View RelatedI have an OLED screen on my laptop that I have configured to show status information. The current driver I have installed in Linux for it is able to display messages by sending them to a script as an argument separated by spaces.Example: the command /opt/asusg50oled/utils/notify.sh Hi Everybody "Hello World" displays on the oled screen:
Hi
Everybody
Hello World
If another message is sent before the old ones disappear and it reverts to status info, it pushes off the top message. Example: less than 30 seconds after the previous example, /opt/asusg50oled/utils/notify.sh "Bananas have potassium" is executed:
Everybody
Hello World
Bananas have potassium
What I want to do is have kernel messages (the kind you see by running dmesg) forwarded to this script. For example, when I insert a USB drive, the following information would show on the OLED screen as they're logged:........
Recently I am trying to install the latest Ubuntu / Xubuntu but after the kernel messages the display becomes corrupted. The machine is a Clevo laptop with the dreaded SIS 671 / 672 chipset. The Ubuntu 8.04 is working flawlessly. Any other version I get several problems and depending on the mood of the system I get a vertical running display ( not readable ) or a left horizontal displaced screen (readable) ...
I tried more tan several CDs ranging from 9.01 to 10.10 both Ubuntu or Xubuntu. What is the plainest (simpler ) VGA mode in order to install it? I have tried vga=normal and even VGA =3 with no success. With the latest Ubuntu 10.10 I get another problem it simply does not recognize the HDD / SSD. I have traced the SSD problem with the sata_sis module in kernel 2.6.35 and up... Other distros have the same problem ...

I think, I can stop kernel logging from /etc/rsyslog.conf, but I wanted to know the real problem.
Is there a way I can redirect messages from kernel ringbuffer to a logfile, e.g. with rsyslogd? With redirect I mean that the messages do no longer appear in dmesg, but only in the logfile.
In my case that should be iptables log messages.
I have been running kernel-2.6.33 (gentoo) with a graphical console which appears after the grub screen. My kernel parameters include `vga=0x317'. Since I upgraded my kernel I have only been able to get a 80x25 text console. If I use `vga=0x317' I get a black screen after the grub prompt. I have tried using `vga=ask' and choosing a number of resolutions - with no luck.
I've tried a "vanilla" 2.6.34 config and also a bootable Sabayon Linux disk with 2.6.34 - with the same result. Interestingly Sabayon Linux eventually fired up X successfully - after a black screen while it was booting.
Its looking like 2.6.34 doesn't like my hardware.

I'm currently doing a tutorial for writing kernel modules. Right now I'm still at the very beginning, i.e. writing my helloworld stuff.
But what I like to do now is to write stuff onto the console, and I don't get it. According to my tutorials I can print stuff on the console using the printk()-function as long as the priority-level of the macro used in printk() is lower than the console_loglevel (how can I find that value out btw?).
But it doesn't work for me. Even if I use KERN_EMERG it still gets only logged, but not printed on the console and I thought KERN_EMERG get always printed...

Recently I did a kernel update (compiling it manually with help of SuSE Automatic Kernel Compiler). Everything works fine and I am happy with my own settings, however there is one thing that I would to enable. On the stock kernel there is a openSUSE bootsplash on startup and a nice looking openSUSE background image in console mode. On my newly compiled kernel there is no such a eyecandies. My question is: How to enable them on my own compiled 2.6.38 kernel?
P.S In the attachment you can see what i mean with that background image in console mode, so you get my point. This is the image found on the internet, my system is openSUSE 11.4 (64 bit)
I'm guessing the answer to my question is in manipulating the kernel command line. But with what arguments? (and does the kernel have it's own fonts to be used on a FB device?)
The host is a ARM9 based embedded system with a 1-bit LCD screen.
This is a prelude question to: Naming a Frame buffer Device
When I load the radeon module, from initscripts, the commandline, or when Xorg loads it, it makes all my consoles go blank. They are still active I can type into them then cat /dev/vcs* from X, and I see what I typed. I am using vga16fb as my framebuffer console driver, and am on PowerPC so I don't think I can use plain VGA consoles.
this is my /etc/modprobe.d/video.conf
